hi all.
i want to write a server health monitoring tool. i want to a tool that periodically check server's availability and alert when any problems has occurred.i searched on google and noticed that i colud use JMX for my case.
but when i read JMX documentation, i have confused. so i need help about how to do this. for example a tool that pings a server every 30 seconds and alerts when the server is not reachable. is any document or help?
thanks in advance
